SAWING SPOKES.

Specification of Letters Patent No. 5,989, dated December 26, 1848.

To @ZZ whom t may concern Be it known that I, THOMAS GREEN, of the townof De Witt, in the county of Onondaga and State of New York, haveinvented a new and improved mode of sawing out spokes, staves, and otherarticles with the grain, whether the lumber from which the same aresawed be straight grained or winding, and I do hereby declare that thefollowing is a-true and eXact description of the said invention.

The nature of my invention consists in sawing with the grain eitherstraight grained or winding timber in such manner as to make the spokeor other article sawed out straight and not cross grained withoutI wasteof timber.

To enable others not skilled in the art to use my invention I willproceed to describe its construction and operation.

I construct a frame (on which the car riage is to run) at least twice aslong as the lumber int-ended to be sawed, near the middle of the frame Iplace two circular saws, one perpendicular and the other horizontal. Theperpendicular saw I place so as to saw the under side of the bolt orblock toward the center and deep enough for the width of the spoke orstave. I place the' horizontal saw as high as the upper edge of theperpendicular saw and so near to it that the cuts of both saws will meetand form a right angle. The carriage runs on ribbons, at each end of thecarriage I place a standard upon which I place a sliding block to beraised or lowered at pleasure to suit the size of the bolt or log sawedfrom, into which are placed the boxes for the ends or gudgeons of theshaft to run in. The ends of the shaft are crooked so that the centersof the ends or bearings are in a line with one side of the shaft. Thelog or bolt to be sawed is to be split as the grain runs, as near as maybe, through the center, into halves. I then place the flat side of thebolt at the center or heart against the side of the shaft that is inline with the center of the bearings or ends, and fasten it there withdogsor staples. The head standard is attached to the carriage by a jointor hinge so that the upper end maybe leaned to or from the saws atpleasure, according to the wind of the grain of the bolt. The shaft isthen turned so as to bring the flat side of the bolt towardfthe saws,the lower edge should be turned far enough` past the perpendicular sawto constitute the thickness of the spo-ke which is regulated by a gage,and the head standardtrained to or from the Vsaws so as to make the edgeof the bolt parallel with the side ofthe carriage,fand fastened there.

Having the bolt thus placed I saw out a spoke. and then turn the boltfar eno-ugh for the thickness of another, andA repeat the process untilone tier is sawed around the bolt. I then lower the head 'and footblocks enough for the width of anothery tier of spokes and gage them sothat the wide end of the spoke is taken from the largestend of theiboltand so continue the operation until thelog or bolt is sawed up.

What I claim as my invention and desire Ato secure by Letters Patent is-The placing the bolt and arranging the operation so that I saw with thegrain, straight grained or winding timber, and makev the spoke or otherarticle sawed straight and not cross grained, Without wasting thetimber.
